DEVICE Eon UPSETTINGoItjLENGTHENING Iiioiv' BAR.

To all whom it may concern Be it known-'that I, WALTER STooK, a' citi' zen of the -United States of America, resid-' ing at the city -of'fAlbany, in the county of lAlbany` and .State of New York', have invented certain new and useful Improve-:1

men-ts in Devices for Upsetting or Lengthen-y ifo? ing an Iron Bar, of which the following is,I a1' specification. y Y

My invention relates to devices for u'psetting or llengthening an liron bar,- and the object of, myin-'vention is to 'provide-a meansy for applying for'ceto'the end 'of a side rod,

pedestalbinder or other` piece of ironwhile IE54i it isheld securely in position,and therebyy shortening it, which device may'also be arranged in-s'uch a manner that the force applied to the endof the piece operated on will ca-use'it to belengthened -by stretching it forward vvhi'le1 it is held securely along thel sides; together with such elements and combinations as are hereinafter more particularly set forth and claimed.

I accomplish these objects by means of the mechanism illustrated in the'accompanying drawing, in which:

Figure l is a'section: along the line 1"-1 on* Fig. 2. Fig. 2 is a plan. Fig. 3 is a. detail"i side elevation, with parts broken away, showing the means for connecting the dial finger with the plunger. Fig. 4 is a section along the line 2 2 on Fig. 2. Fig. 5 is a plan showing a piece of iron placed in position for being shortened, Fig. 6 is a plan showing a piece of iron in position for being lengthened. Fig. 7 is a side elevation, partly in section, of the device with piece of iron as in Fig. 6.

Similar letters refer to similar parts throughout the several views.

It is often necessary to shorten or upset a binder or side rod, or other piece of heavy iron, especially in a railway car repair shop, and it is necessary to keep the rod, binder or other bar straight without being curved or bent at the end, which is liable to occur after the bar has been heated and it is pounded or submitted to blows for the purpose of reducing its length. I have arranged a device by means of which the iron bar is securely gripped and positively held against a steady force exerted preferably'by means of a hydraulic ack, screw or similar arrangement applied at one end of the bar. In order to accomplish this result, I provide Specification o! Letters Patent. Patented Noir, 17,1914, Application 'filed Mayl. 1913. Serial No. 76"?,767-

tion of "which I form the groove, B,'and;

through a Wall, C, inthe frame and on a line' with the bottom-of? the groove, B, I recipro; cate the ram, D'. In the chamber, E, of: the' frame I place the toggle, F, beneath the con-1 necting.- links of which toggle, F, I place, preferably, a hydraulic jack, G. On each; side of the groove, B, and near one end, thereof Ivpla'ce the cam-shaped grippingi blocks, H, H. These cam-shaped vvblocks areI so arranged that' when an ironbar is placed in the groove, the blocks maybe made to engage the 'sides of the bar and any move# ment ofthe barwill'tend to force the blocks, tighter and make the bite of the blocks into the bar sharperand deeper. In the'uppery surface of a part of the frame, A, I also pro"- vide a groove, J which isin alinement with, although, preferably, the bottom of this groove-is of less altitude than the groove, B, and is provided along its sides With the grooves, b, to permit of the reciprocation off the lateral projections, fn, at the bottom of' '-'t'o the gripping blocks, H, H, and in the bottom of the groove, J, I place a series of holes, M, through which a bolt, N, may be placed behind the block, K, and prevent the block from moving toward the rear end of the groove, J. The projections, n, at the bottom of block, K, sliding in the grooves, b, keep the block in the frame as against any tendency to rise out of the frame during the application of pressure to the work. As thus arranged, when an iron bar W suitably heated is placed in the groove, B, with its end against the block, K, and the bolt, N, placed through one of the openings, M, and the ram, D, against the end of the bar, when force is applied to the toggle, F, the bar W may be upset without bending, curving or interfering with the operating shape of the end of the bar.

When it is desired to lengthen the bar W, it is placed on the block, K, and in engagement with the gripping blocks, L, and also in engagement with the gripping blocks, H, H An iron rod, X, is placed between the ram, D, and the block, K, as shown in Figs. 6 and 7, and then force is applied to the toggle, and as the block, K, is moved in the groove, J, the bar W will be drawn out or H, H, and L, L, hold theside's ofthe bar firmly and the constant and irresistible presout the bar because of the block, K, being mDYable the gratuite.,J..4 1,; 'A Y For the purpose of straightening or bending a bar it may be placed transversely of thefrarne, .between jthepairr of griplling1 hlgksf H: Ha :Indalia the'blck K; being? h-ffd the 110111,- Nimes@ the/iron radi placed the groove, B-resting against the Lent-, ,which may be. ae-ted upon by the ram, i. z
